expand (1-t)/((1-t(1-x))^2)

expand

\frac{1 - t}{( 1 - t ( 1 - x ) ) ^{2}}

\frac{1 - t}{2 t x - 2 t ^{2} x + t ^{2} x ^{2} - 2 t + t ^{2} + 1}

Solution steps

\frac{1 - t}{( 1 - t ( 1 - x ) ) ^{2}}

(1 - t (1 - x))^{2} = 2 t x - 2 t^{2} x + t^{2} x^{2} - 2 t + t^{2} + 1

= \frac{1 - t}{2 t x - 2 t ^{2} x + t ^{2} x ^{2} - 2 t + t ^{2} + 1}

c u r l (x^{2} y, yz, x - z)

x^{2} + (\frac{4 x}{x - 2})^{2}

\frac{3 x}{2} - \frac{3}{2 π} (100 - 3 x)

\frac{( z ^{2} + z )}{( ( z - 1 ) ( z ^{2} + 1 ) )}

\frac{2 x ^{2}}{( 2 x - 1 ) ( x + 1 )}
